BRICK-PRESS.

Specification of Letters Patent.

Patented July 17, 1906.

Application filed August 5.1905. Serial No. 272,939.

To all whom, it may concern:

Be it known that I, FRIEDRICH MUELLER, a subject of the Emperor ofGermany, and a resident of St. Louis, Missouri, have invented certainnew and useful Improvements in Brick-Presses, of which the following isa specification.

My invention relates to improvements in a brick-press; and it consistsof the novel fea tures hereinafter described and claimed.

The object of my invention is to construct a machine for forming andpressing brick out of dry clay and to expel the pressed form from themachine automatically.

A further object of my invention is to provide a mechanism whereby thetension or pressure applied to the dry clay may be adjusted to thedesired degree of pressure for forming a brick.

In the drawings, Figure 1 is a side elevation of my complete invention.Fig. 2 is a Fig. 3 is a vertical longitudinal sectional view taken onthe line 3 3 of Fig. 2. Fig. 4 is a side elevation of my inventionopposite to that of Fig. 1,. Fig. 5 is an end elevation of my inventionviewing the same in the direction indicated by the arrow 5 in Fig. 1.Fig. 6 is a vertical cross-sectional view taken on the line 6 6 of Fig.2. Fig. 7 is a detail perspective view of one of the side brackets madeuse of for raising and lowering the upper set of dies. Figs. 8 and 9 aredetail views of the cams made use of in carrying out my invention. Figs.10, 11, 12, and 13 are vertical sectional views of a portion of themachine, showing the positions of the dies and operating-cams during themethod of forming a brick. Figs. 14 and 15 are a plan and side elevationof the ad justing device. 7

In the construction of my invention I provide a suitable frame 14,mounted upon a base 15. The upper portion of the frames are connected toa table 16, composed of two parts, and in the intervening space betweenthe two sections is located the mold formed. Upon the top of the tableand to one side of the -mold is located a hopper 18, in which the clayis placed and from which it is fed into the mold by means of a conveyer19. The conveyer 19 is provided with pockets 20, by which the clay isfed from the hopper 18 into the mold 17 the operation of which will. befully hereinafter described. In the frames 14 are provided suitablejournals 21, in which is revolubly mounted an operatingshaft 22. On thisshaft is mounted a large gear-wheel 23, with which meshes a pinion 24,mounted upon a driving-shaft 25, supported in suitable bearings formedin the frame 14 and placed in operation by means of the pulley-wheel 26.

Upon the operating-shaft 22 are mounted the cams 27 and 28, the cams 28being located one on each side of the cam 27 and being designed to comein contact during the revolution of the shaft 22 with the rollers 29,mounted upon a shaft 30, which shaft is supported in a pair of sidebrackets 31, one located on each side of the machine-frame and guidedbetween ribs 32. The upper ends of the side brackets 31 are bentinwardly and securely fastened to a die-head 33, to the under surface ofwhich is provided a pair of dies 34, which operate in the mold 17, inwhich the clay is pressed.

The cam 27 during the operation of the machine is designed to come incontact with the roller 35, which is located in a die-block 36, whichoperates a pair of dies 37, formed on the upper surface of said block,and which presses the clay within the mold 17 in conjunction with thepressure brought upon the clay from the dies 34. The die-block 36 isguided between the ribs 38, formed on the inner surface of the frames14, and is adjusted to the required movement by an adjusting device 39,which consists of a bifurcated frame 40, having inclined surfaces 41,which is brought in contact with the under surfaces of the side portionsof the die-block 36. bifurcated 'frame 40 is located and guided uponbars 42, formed on the inner surface of the side frames 14, and saidbifurcated frame is held in position by a cross-bar 43, securely boltedto the side frames 14. To the crossbar 43 is mounted an operating-screw44, which is screw-threaded, and by the manipulation of the hand-wheel45 will operate the bifurcated frame 40 inwardly and outwardly, asdesired, to raise and lower the die-block 36 to any height desired.

Upon the operating-shaft 22 and located on the outside of the frames 14are provided cams 46, which during the revolution come in contact withthe rollers47, carried by the side brackets 31, which raise and lowerthe brackets by the contact of the cams and raise and lower the dies 34in and out of the The IIC

mold 17 for the admission of the clay and to press the same. Thevertical motion of the side brackets 31 is permitted by means of theelongated slots 48. In the gear-wheel 23 is formed a camway 49, in whichoperates a roller 50, carried by a lever 51, mounted upon a shaft 52,which extends through the side frames 14, and on the opposite end ofsaid shaft is connected a lever 53. On the upper ends of the levers 51and. 53, which are lo cated in alinement with each other, are pro videdelongated slots 54, and through said slots project a shaft 55, whichextends through the conveyer 19 and by the manipulation of the levers 51and 53 feeds the clay from the hopper 13 i'itc the mold 17. Thisoperation is done by the formation of the camway 49 and at a period whenthe upper dies 34 are in elevated position, so that the conveyer mayfreely pass beneath the dies 37 to remove the brick which has beenpreviously pressed and at the same time to refill the mold for a repeated compression. The conveyer 19 is held in position upon the tableby means of the guide 56.

The operation of my invention is as follows: The clay, which may beeither in a dry or moistened state, is placed within the hopper 18 whichwill necessarily-fill the pockets 20 of the conveyer, and while theupper die is in its raised position and at that period by themanipulation of the camway in the gearwheel will operate the levers 51and 53, bringing the conveyer 19 forward over the mold 17 and permittingthe clay carried by the pockets 20 to fall Within and fill up the mold17, and during its return the sides of the pockets act as a scraper toremove from the mold all surplus clay. At the instant the conveyer isbrought to its normal position the upper dies 34 begin to descend bymeans of the cams 28 coming in contact with the rollers 29, pullingdownwardly upon the side brackets 31. At this instant the center cam 27comes in contact with the roller 35, slightly raising the die 37, whichimparts an upward compression upon the clay within the mold 17. Then thehighest point of the cam 27 begins to raise the die-block 36 and dies 37and at the same time the highest part of the cam 28 is released from therollers 29, and the cams 46 begin to contact with the rollers 47,raising the side brackets 31. During this period both dies 34 and 37simultaneously rise until the contact surface of the die 37 is in ahorizontal plane with the table. At this period the form of compressedclay is delivered from the mold. Then the conveyer begins to advance andpushes the form forward and automatically fills the mold for a secondcompression. The abrupt offset 57 formed in the cam 27 is to per mit thedie 37, die-block 36, and roller 35 to to its normal position at themoment the fall brick is removed from the mold and provide sufiicientspace for the refilling of the'mold by the conveyer.

The rotation of the chine is in the direction indicated by the ar row X.

In Figs. 10, 11, 12, and 13 the machine is shown in its four distinctoperations. Fig. 10 shows the lower die in elevated position, thecompressed form of clay being delivered from the mold, and the conveyerin the act of passing over the mold ready to fill the same. Fig. 11shows the lower die in its lowest position, the mold filled with clay,the compressed form removed from the mold and resting upon the table,and the conveyer ready to be brought back to its normal position. Fig.12 shows the mold filledwith clay, the upper die descending and in theact of compressing the clay within the mold. Fig. 13 shows both of thedies in their compressed position and the clay within the moldcompressed to the form desired. The next operation will be similar toFig. 10.
